Hi, I’m David Portelli 👋

With over 8 years in product development, I balance hands-on product design with leadership duties. My journey spans startups to public companies, working on both customer-facing experiences and internal tooling. I’m passionate about crafting products from scratch - turning ideas into innovative solutions - and thrive in ambiguity and complexity.
